o cll whom it 'may concern.-

Be it known that I, H. G. `N OBL'E, of Selma, in the 4(county of Dallas,and Starte lof Alabama, yhave in-i' vented a, new and improved Roofing;'nud I `do hereby i declare that the following is a. full, clear, andexact description thereof', which will enable others skilled in the nrtto make and use the seme, reference being had to the accompanyingdrawings, forming perl; of this specification. ,l g

rThis invention relates to improvements-in roofing, and consists i'ncoveringroofs with sheet-metnl, laid on the rafters, and nailed thereonat' the edges, so .as to be coilsidernblyconcaved between ther'n, the,joints `on the rafterslbeing covered by inverted cops or troughs.

The` conczwe form ofthe sheets isdesigned to prevent the sheet-mettli'om'cracking-to whicht is subject, by expansion and contraction, when laidon lint'. Figure 1 represents o perspective View ofa. building `provided'with my improved varrangement of sheetmetnl covering, and

` Figurefl represents e sectional detail.'

Similar letters of reference indicate corresponding pa-rts.-

I take sheets, A, of iron, or other substance, enough wider than thedistance from centre to centre of the rafters to admitof binding down'inthe concave forno .loeinveen` .the rafters, ind nztil them on, itsshown, lie- .ginning at the bottom, and lapping the upper sheets overthe lower` ones, in the usual way.

-' The sheets B, n-t the ridge, I bend over, the same on both sides,eoncwing the ends vbelow the ridge in the snmenvny, biit at the ridge,owing to the ridgepole,l the sheets will represent a.b horizontal line.

Over the joints at the edges' of the sheets on the. rafters, I pince theoeps C, with the sides d fitting snugly down 'on' 'the sheets A B, :tta) suieient dis tance from the joints to prevent* the min from rising nplto the joints, no matter how :noch it may be driven -under Ithe edgesof the sides by the win'd in storms,

The sheets `maybe madewide' enough to stretch over two or more spaces,and be previously shaped as required. n Y

Hoving thus described my invention,-

I claim as new, ond desire to secure by Letterr Pntent` The arrangementof the sheets A B, in the conca-ve form, between ,the rafters, and ofthe caps or troughs C at the-,joints over the rafters, all substantiallyas l specified. ,v
